Answer 1

Answer:

1 )2×2-4=0

V.13:00hrs

2)20

train took 13 hours

Answer 2

1)Time he departed = 7am

Time he arrived = 20 pm

Now,

Time passed between 7am and 12am = 5 hrs

Time passed between 12pm and 8pm(20:00) = 8hrs

Total time passed = 8hrs + 5hrs = 13hrs

Hence, 13hrs took. 2) No. of cars manufactured in 2 years = 72

No. of cars manufactured in the first year = 52

No. of cars remaining = 72 - 52 = 20 Hence, 20 cars were manufactured in the first year
